A bomb sensor

Abstract

The invention relates to the technical field of sensors, in particular to a missile-borne sensor. Including the projectile body, a fiber grating sensor is arranged on the inside of the projectile near the warhead, an optical fiber demodulator and a data acquisition device are arranged side by side on the rear side of the fiber grating sensor, and a single chip microcomputer and a wireless The data sending module chip, the radio frequency antenna and the receiving chip are sequentially arranged between the wireless data sending module chip and the fiber grating sensor from back to front. The present invention designs and uses fiber grating sensor technology to monitor the environmental temperature, pressure and other parameters of the projectile, and provides the monitored parameter information to the computer in time, and makes corresponding adjustments to the projectile parameters and ballistic trajectory after data comparison. It can hit the target more precisely. Among them, the fiber grating sensor is intrinsically safe, easy to install, sensitive and reliable, and has strong environmental adaptability. At the same time, it adopts computer control throughout the process and has a high degree of systematization.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a missile-borne sensor. Background technique [0002] In a complex and changeable environment, ammunition during flight will be affected by the external environment in different ways, such as abnormal temperature changes, changes in the angle of the projectile body, and different pressures. These factors will affect the flight trajectory of the projectile, thus making it impossible to accurately strike the target. Among them, the missile-borne sensor is an indispensable part of the intelligent ammunition to autonomously perceive environmental information or receive instructions. If the environmental information received by the missile body can be monitored in time and fed back to the computer, it will certainly increase the accuracy of hitting the target. Because there are many uncertain environmental factors during the flight of ammunition, the sensor device installed on the am...

AI Technical Summary

Problems solved by technology

At present, traditional electricity-based sensors, magnetic sensors, etc. cannot meet the high accuracy requirements of ammunition strike targets, nor can they be applied to unknown and changing environmental conditions.

Among them, in electrical-based sensors, conventional electronic systems will fail in harsh environments, affecting the measurement of environmental parameters
